I admit that as I've seen the original and read the manga, the pacing of Brotherhood seems to start off being VERY fast (I finally got used to the pacing after watching the first fifteen eps or so). Events that took up half a volume of the manga and had spread though a few episodes of the original anime were now shown in just a single episode. However, after trying to look at it from the perspective of someone who's new to FMA (not comparing it to the manga nor the original), I believe that the pacing works and it manages to tell an intriguing story effectively with little confusion. The plot is full of clever ideas and unpredictable twists that link various parts of the story together. By the final episode, all loose ends are neatly tied up and what's left is a hugely satisfying epilogue.
The animation in FMA Brotherhood is crisp and very well done (although it does sometimes dip a bit in quality). Compared to the original FMA it's a bit simpler but that's just because the original set a very high standard to follow. The facial emotions of the characters are also perfectly presented. The action scenes are brilliant and VERY well animated, with a variety of alchemy techniques and other talents being displayed nearly every episode. The various battles are consistently exciting to watch, but somehow get even better towards the end of the series.
The voice acting is of an excellent and consistent quality, and I think that pretty much all the characters have voice actors which suit their personalities. The majority of the openings/endings are a pleasure to watch due to fantastic animated sequences and theme songs. The background music which play during the episodes usually fit very well with the situation, although some tracks seem to be overused a little at first. This becomes less of a problem as the series progresses, with plenty of new music being introduced to support the story as it reaches the finale.
Moving on to the characters (best thing about this series), the original FMA focussed mainly on Ed and Al and on their struggles to regain their bodies, whereas Brotherhood also explores other characters to great detail at the same time. The majority of the spotlight is still on the two brothers, but it highlights their interactions with new characters which were not present in the original anime. New characters include a group of people from Xing (a neighbouring country), another person from the Armstrong family (who I think has become one of the coolest members of the supporting cast), and a new main antagonist. For me, the Xingese characters in particular (Ling Yao and Mei Chang among others) provide a new dimension to the FMA world, by showing us a different culture to the militaristic one we're familiar with. I think the new antagonist is an improvement on the original FMA, as this person has a much stronger and clever link to the Elric brothers' father. Returning characters from the original FMA, such as Mustang and Scar, are much more awesome and developed due to the fact that Brotherhood is 100% faithful to the manga. Plus, Winry Rockbell now has a much more active role in the story. I can say for sure that this anime has one of the best main/supporting casts I've ever seen, and you'd probably find it difficult to label any of the recurring characters (whether they are good or evil) as being either boring or unnecessary in terms of the storyline.
One of the many good things about this series is that there has been absolutely no filler at all (yes, I'm thinking of Naruto, Inuyasha, etc), which prevents the story from losing momentum. All the episodes are concise and every scene is important as part of the huge plot. The dialogue fully explains everything and is straight to the point. As multiple characters are explored there are lots of side stories, but these are all perfectly intertwined with the main story of the Elric brothers and more often than not directly influence their journey too. Like most anime series, there are things from the manga which have been left out, but these are usually just restricted to comedy moments. There has been one episode which shows a lot of flashbacks of events so far, but that's forgiven as it shows the most epic moments of the series, and also provided us with some history on the father of the Elric brothers.
FMA Brotherhood will be sorely missed now that it's finished. It is excellent in every aspect and has very little, if anything, that can be called a flaw (maybe rushed character development at first due to the fast pacing, but this quickly subsides). Each episode feels like it's too short, a testimony to how much it draws you in to the story and characters. There are moments which leave you smiling, laughing, sad and simply amazed. Try this anime, it's recommended for absolutely everyone, to newcomers and to those familiar with Fullmetal Alchemist.
